MACHINE FOR CUTTING PADS OR TABLETS.

SPECIFICATION forming part of LettersPatent No. 758,156, dated April 26,1904.

Application fil d July 31, 1903. serial No. 167,684. (No mode h) To allwhom it may concern..-

Be it known that I, CHARLES F. TAYLOR, a citizen of the United States,residingatHartford, in the county of Hartford and State of Connecticut,have invented certain new and useful Improvements in Machines forCutting Pads or Tablets, of which the following is a specification.

In making pads or tablets for wrlting, drawmg, or other purposes thedesired number of long sheets of the paper that is to be used are piledup and bound along one edge, forming blanks ofconsiderable length. Theseblanks are then by a trimming-knife divided into pads or tablets of therequired size.

This invention relates to a machine for dividing the blanks into pads ortablets of the desired size.

The object of this invention is to provide a simple cutting-machineinwhich a number of blanks of any ordinary length each containing thedesired number of sheets of paper Y bound along one edge may be placedand automatically fed to a stop which locates the blanks so that theywill be accurately out.

Figure l of the accompanying drawings shows a plan of a machine thatembodies the invention. Fig. 2 shows a front elevation of this machinewith parts cut away to expose the mechanisms. Fig. 3 shows a verticalsection taken on the plane indicated by the dotted held onthe upper edgeof a plate 7. The

edges of the cutter-plate 5 and the supporting-plate 7 extend intovertical openings 8 in the side frames, Figs. 2 and 3. Apin 9 projectsfrom the cutter-plate into an inclined groove 10 in a bracket 11,attached to the under side of the table, so that the cutter will begiven a shear when it is raised. Strips 12 connect the lower edge of thecutter-plate with the supporting-plate, so that the cutter-plate will bedrawn down when the supporting-plate is lowered, Fig. 3.

Extending through the lower part of the supporting-plate is a shaft 13,on each end of which 7 is a gear 14. On each side a rod 15 connects acrank-pin projecting from a gear 14 with a cross-head 16, that extendsthrough the openings in the side frames and carries a clamp% ing-bar 17,Fig. 3. Attached to each endof the cross-head is a vertical rack 18,which meshes with a segmental rack 19, attached to a transverse shaft20, Figs. 1 and 2,-so that bothends of the cross-l1ead will movetogether.

Links 21 connect the shaft 13, that extends through the lower part ofthe supportingplate, with a shaft 22, that is supported by links 23,that hang from a shaft 24, fixed to which is a driving-pulley 25. Theshaft 22 has a pinion '26 at each end which meshes with a gear 14, andthis shaft also has a gear 27, that meshes with a pinion 28 on thedriving-shaft 24, Fig. 2. By means of this mechanism when a number ofpad or tablet blanks are upon the table above the cutter the-rotation ofthe driving-pulley through the pinions,

gears, and cranks first causes the clampingbar to be drawn down so as toclamp the blanks to the table above the knife. Then after theclamping-bar has been moved as far as the blanks will allow thecontinued move ment of the pinions, gears, and cranks causes thecutting-blade to be lifted so as to divide the blanks from below. Whenthe cutting:

blade is lifted, the pinions and gears are kept in mesh by means of thelinks. After a out has been made the blade is loweredand theclamping-bar is lifted.

The blanks are pushed between a fixed guide 29 back of the middle of thetable and an adjustable guide 30 in front of the-middle of the table bya feed-knee 31, attached to the rack 32., that is movable in a way'33 inthe top of the table, Fig. l.

Meshing with the rack is a pinion 34 in mesh with a pinion on the shaft35, that has a clutch 36 between two beveled gears 37, that mesh with abeveled gear 38 on a shaft 39, Figs. 1 and 2. When the clutch is thrownto one position, the knee is fed forwardly, and when it is thrown to theopposite position the knee is fed backwardly. The shaft 39 is providedwith a friction-disk 40, that is forced against a friction-disk 41 by anadjustable spring 42. The friction-disk 41 is on a shaft 43, that has abeveled gear 44, meshing with the beveled gear 45 on a shaft 46, thathas a gear 47, in mesh with which is a gear 48, that meshes with thepinion 28 on the driving-shaft, Fig. 2. By means of this mechanism thefeed mechanism is rotated continuously, and if there is no resistancethe knee feeds the blanks forwardly; but after the blanks have beenbrought to a stand by a stop the feed-knee remains stationary and thefriction-disks slip.

In the machine illustrated a rotary stop is provided for limiting theforward feed of the blanks. Above the table beyond the cutter are fourwings 49, each of which may be pro-' vided with an adjustable stop 50,Fig. 1.

These wings are attached to a post that is sup ported by a sleeve 51,fastened to a slide 52. that is held by a bracket 53, secured to theunder side of the table. The slide isconnected by a link 54 withthe-supporting-plate 7, so that when the supporting-plate is raised theslide, with the wings and stops, is carried away from the knife, andwhen the plate is lowered the stops are drawn toward the knife.

On the slide is a segmental rack 55, meshing with which is a verticalrack 56, that has its lower end pivoted to the supporting-plate 7 andits upper end connected by a link 57 with the slide, Fig. 2. Attached tothe lower end of the post to which the stop-wings are fastened is anindex-disk 58, Movable on the post above the index-disk is a ratchet-arm59, that is connected by a link 60 with the segmental rack. arm is apawl 61, that is adapted to engage the notches in the index-disk, Figs.2 and 4. When the cutter is lifted, the vertical and segmental racksdraw the ratchet-arm back, and when the cutter is lowered these rackspush the ratchet-arm forward and cause the ratchet to feed theindex-disk, so as to rotate the stop-wings. Four stop-wings are shown,and consequently there are four notches in the index-disk, and that diskand the Wings and stops are fed ninety degrees at each forward movementof the ratchet.

A lever 62 is pivoted to an arm 63, that projects from thesupporting-sleeve in such position that its lower end is adapted toenter the notches and lock the index-disk against movement, and itsupper end is adapted to engage a wedge 64, Fig. 4. When the slidecarries the parts back, the lever 62 is oscillated so as to unlock theindeX-diskand allow it to be rotated. A spring 65 is arranged to drawthe lower end of the lever into the notches and stop the disk in thecorrect position.

Each time that the stop-wings are rotated a bunch of pads or tabletsthat have been out On the outer end of the ratchet-- from the blanks bythe reciprocation of the cutter are swept around onto the endless belt66 and another stop is brought into position for determining the feed ofthe remaining blanks. A curved flange 67 is attached to the top of thetable to guide the pads or tablets as they are swept around by therotation of the stop-wings onto the endless apron, Fig. 1.

The endless belt passes over a pulley 68, located at the rear of one endof the machine on a shaft which has a gear 69, that meshes with a gear70 on a shaft 71, that extends along the back of the machine and has abeveled gear 72, meshing with a beveled gear 73 on the shaft 46.

The stops are first adjusted on the stop-wings so that the distancebetween them and the edge of the cutter-blade will be the exact size ofthe pads or tablets which are to be cut from the blanks.

The blanks are placed upon the table in front of the feed-knee. Then thefeed-clutch is thrown so that the feed-knee will push the blanks forwarduntil their ends engage a stop. When the blanks are stopped, thefrictiondisks slip and the knee holds them in position againstIthe stop.At this time the cutterclutch is engaged, so that the clamp-bar will belowered until it clamps theblanks down to the table, and then the cutteris drawn up, as explained, and divides the blanks. cutter rises and cutsthe blanks the stop is pushed back by the mechanism described, so thatthe pads or tablets which are cut from the length of the blanks can moveaway from the blade and allow it to pass up through all of the blanks.As the cutter is lowered and the clamp-bar is raised the stop-arms arerotated, andthe pads or tablets which have been out are swept onto theendless apron and carried off, while another arm is moved into positionto locate the blanks which are fed for ward by the feed-knee as soon asthe cutter is below the table. The blanks are fed forward after the cutpads or tablets have been re moved until the entire length of blanks hasbeen divided into pads or tablets. The knee feeds the blanks each timeclose against a stop, so that the pads or tablets will-always be cut thesame size, and these will be cut squarely, for they are fed between thefixed guide on one side of the table and the adjustable guide on theother side of the table.
